Relay Actuator With Pushbutton

This example show how an relay controlled locally at the Arduino with an push button. The Relay can also be controlled from Vera. The push button changes of the relay state will also be transmitted to Vera.

Software

Wire things up

Follow the instructions in ConnectingRadioModule to connect radio module. Connect the IN1 of relay to digital pin 4 of Arduino board.
Connect Relay VCC to +5V of the Arduino board. GND to GND.
Connect push button between +5V and digital pin 3 with a 10k pull down resistor to GND (see image).
